The glyph up arrow (or pike, in A Dictionary of APL) is an upwards pointing arrow represented by the Unicode character ↑, "upwards arrow". The up arrow has several uses in various dialects:
- In all dialects,
↑is Take when used dyadically (except very early versions of APL\360, which used it for Rotate). - In SHARP APL,
↑is Nub when monadic. - In APL2, NARS2000, GNU APL, and APLX,
↑is First when monadic. - In Dyalog APL, dzaima/APL, and ngn/apl,
↑is Mix when monadic. - In A+,
↑is Signal, giving an error with the specified message, when monadic.
